To all? whom tamer concern:

Beit known that LHENnr GARANT, a citizen of the United Statesof. America, and resident of: Y Chattanooga, --county.of- Hamilton ,1 State of Tennessee, have, invented 'cert'aina.

new-and guseful- :Improvements'in Dial Knit ting-Machine s, of'whiclrl the following-is afulli and: 4 clear specification, reference, being;

Myinventi'on relates to that class of-knit'- ting machines forproducing ribbed work,

'whichremploy two sets of needles, one set working horizontalland the otherset-vertically, and means 'eing provided to auto matically" effect the production of slack coursesin the tubular fabric, so that the ribbed tube may be severed into lengthsand Y beusedforthe tops of half-hose, cnfls' for shirts and drawers, etc. I

- Theobjectof my vention-istoprovide an extremely simple attachment whereby this loose or slack course'will bemade much larger, and to effect this I provide means whereby 'the' horizontal needles will be elevated'si-mul-taneously with the depression ofthe: vertical need-les,.;therebydrawing the loopsout in opposite directions and concourse, as more 'fully hereinafter'setforth. Referring to thedrawings by referencecharacters, Ais the fixedirame or bed of the machine,*B the-fixed cylinder for the vertical needles, and D the fixed circular dial carrying f the horizontal needles.

. E is the rotating cam ring for operating the vertical. needles, and F the rotating cam plate f orv operating; thgay horizontal needles,

' thering E being .dfivehgbyzuitable bevel gearing'from thedriving shait in'the usual manner, and the cam plate F being'suspended from and adapted to rotate with the arch E of thecamring E.

devices are to be brought into play. When" raised, this cam C is adapted to. actuate tap.-

" All the foregoing-devices are common, to

circular dial machines'andthey neednotbe more-fully described herein.

he waveelikeumovement oflthe vertical needlesisindicatedvby the heavy dotted line a M.,- and; the movement of the horizontal needles causedby my attachment is indicated by the heavv dotted line. N, 'itbeing observed that i at Othe projecting heads: of

these needles ar'eraised, this elevation of the horizontal needles being coincident with the depression ot the vertical needles so that the two waves travel together around thedial."

In'thisway I-cause both sets-of needles to take anactive art in the drawing out o i-the a loose course, thus securing loops forming a wider and looser course than is possible where, as heretofore, the horizontal needles alone have. been actuated to roduce this elevation of. the horizontal needles by any suitable mechanism, the-specific mechanism slack course. I may-produce t is wave-like I employ being dependent upon the particularmachine in whichthe invention is embodied. In that e of machine I have shown Ihave found t at the simplest way to roduce this action of the horizontal nee es is to tapinto the upper end of screw K a tappet screw P, and arrange in the'path of the upper end of said tappet an 11 wardly swinging plate Q which 1s 'pivota y supported on a pivot "screw R and extends m-' wardly toward the ringvB and is provided at its inner edge with a cam S whose upper cam surface is adapted to be elevated into the path of the horizontal needles when the ta pet P is swung in under plate Q to lift t e same. The cam carryin late Q- has its under surface beveled at (i ownwardly and inwardly sothat when the up er end of ta pet P is moved inward towar the ring B t e cam S will be raised and held up during. the

rotation of the cam ring E, at the same time and coincidentl r with the depression of thevertical needies. By adjustingthe screw P the length of loop may obviously be regulated. To support .the plate Q in the proper position a lug- Q thereon engages a lug T carried on the bracket U which is attached to the cam ring E.

It will be obvious tothose skilled in the art that various mechanical embodiments of the invention are possible and'I, therefore, do not wish to be limited to the exact arrangement and construction shown.
